Abstract
Our results suggest that positive and negative urgency are associated with increased activation of general, positive alcohol cognitions, rather than mood-specific subtypes....

Abstract
We introduce a distinction between urgent and evaluative behaviors. Urgent behaviors are performed under high time-pressure and, when successful, they will help to avoid high negative outcomes. According to some social psychologists, evaluation is considered a type of value categorization (for examp...

Abstract
Changes in face expression recognition and EEG synchronization arising from additional load on working memory were studied in healthy adults. Two types of additional task--semantic and visuospatial--were used to load working memory in an experiment with a visual set, formed to facial stimuli. During...

Abstract
Unfulfilled expectations can lead to patient dissatisfaction with surgical outcomes. Understanding expectations allows surgeons to identify those patients who hold inaccurate expectations preoperatively, and to reset those expectations through focused preoperative education. The purpose of this stud...

Abstract
We report two experiments that were designed to adjudicate between these accounts. In Experiment 1, membership was manipulated on a trial-by-trial basis by cuing the possible responses for each trial. Response time (RT) was longer for distractors that corresponded to a cued, eligible response than t...

Abstract
We did not find any differences between long-term recovered subjects, weight-restored AN patients and those in an acute phase of their illness. AN subjects were significantly more likely to be left-handed than healthy controls (OR=2.8, 95% C.I. 1.1-7.2).
Set-shifting and central coherence seem to be...

We found differential brain activations to the verbal and social cues embedded in the choice problems. In large group contexts, framing effects were significant where participants were more risk seeking under the negative (loss) framing than under the positive (gain) framing. This behavioral differe...

Abstract
We have previously shown that elevating noradrenergic activity in rat medial prefrontal cortex (mPFC) can facilitate cognitive set-shifting, and that chronic unpredictable stress (CUS) caused set-shifting deficits. It is not known, however, if noradrenergic modulatory function is compromised by chro...

Abstract
We investigated whether involuntarily directing attention to a target-colored distractor causes the corresponding attentional set to enter a limited-capacity focus of attention, thereby facilitating the identification of a subsequent target whose color matches the same attentional set. As predicted,...

We investigated gray matter correlates of set-shifting while controlling for component processes.

In the first of two recent papers, Pekala, Kumar, Maurer, Elliot-Carter, Moon and Mullen (2010a) review what they consider to be the relationships between trance or altered state effects, suggestibility, and expectancy, and how they relate to the concepts of hypnosis and hypnotism. They also suggest...

We provide evidence for the existence of inattentional blindness (IB) in a real-world basketball setting among adults (Experiment 1). In Experiment 2, we found that players with hardly any basketball experience were more likely to experience IB in a real-world basketball setting, as compared with ex...

How constant is the Weber fraction (WF) for brief time intervals? This question was assessed in three experiments with two base durations (BDs), 0.2 and 1 sec, and with different ways of estimating the WF. In Experiment 1, the psychometric functions were drawn on the basis of 4, 8, or 12 comparison...

We used a two-phase learning procedure in which learners were presented with learning input referring to two interconnected causal relations forming a causal chain (Experiment 1) or a common-cause model (Experiments 2a, b). One of the three events (i.e., the intermediate event of the chain, or the c...

Brain activation in depression during expecting events of unknown emotional valence was comparable with activation while expecting certainly negative, but not positive events. This neurobiological finding is consistent with cognitive models supposing that depressed patients develop a 'pessimistic' a...

Fiedler and Kareev (2006) showed that small samples can, in principle, outperform large samples in terms of the quality of contingency-based binary choice. The 1st part of this comment critically examines these authors' claim that this small sample advantage (SSA) contradicts Bernoulli's law of larg...

Changed state anxiety observed after CBM-I is not a valid indicator of a causal relationship. The finding that CBM-I affected interpretive bias, which in turn affected trait anxiety, supports the assumption of a causal relationship between interpretive bias and trait anxiety. This is promising in li...
